Specification of Letters Patent.

Patented June 2, 1914.

Application filed January 13, 1913. Serial No. 741,892.

To all whom 1' t may mum/w.

Be it known that I, From I). CLARKE, acitizen of the United States, and resident of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Scoring-Machines, of which the :t'ollowing is a specification.

This invention relates to machines for scoring paper-board, and particularly to machines of that class known as doublescoring machines, in which. separate sheets of paper-board are fed lirst through pri mary scoring mechanism in one path and then through secondary scoring mechanism in a path usually at a right angle to such first movement to score the sheet along lines perpendicular to each other.

The present invention has for its principal object to provide a machine of this class in which the movements of successive sheets into and through the machine are positively controlled, and also to provide a machine of this class capable of operation at high speed.

l n carrying the invention into effect means are provided for presenting successive sheets to the machine in such manner as to assure a positive cooperation of all of the elements that operate upon said sheet during its passage through the machine, timing means be ing employed for preventing the delivery of a sheet from the tirsl'. feed-table to the primary scoring mechanism except at a predetermined point in the cycle of operations of the machine. which point in the machine illustrated herein is always the same for each cycle of operations.

in general, an. important object of the invention is to provide a Matilde-scoring machine in which all of the parts are so organized as to move in a certain predetermined timing in cooperation with one another, and to present each sheet to the receiving end of the machine at such a time that in its travel through the machine said sheet will find the successive sulrmechanisms and elements r ady to receive it and operate upon it without loss of time and w ithout any interference of a sheet traveling in one path through one of the scoring mechanisms with a. sheet traveling in another path through the other scoring mechanism.

Other features of the invention not herembefore referred to will be hereinafter described and claimed and are illustrated in the accompanying drawings, in which- Figure 1 is an elevation of the machine looking from the left-hand side thereof; F 1g. 2 1s a plan partly broken away and in section, showing a part of the primary scoring mechanism and the timing means cooperative therewith, and also the reciprocatory feed-device and the means by which it is operatcd; Fig. 3 is an enlarged sectional new of a portion of the machine looking from the left-hand end thereof and showing the principal elements of the timing means, the section being taken on line 33 of Fig. 2; Fig. 4: is an enlarged sectional elevation, looking from the rear of the machine, illus trating certain of the operating connections to the reciprocatory feed-device and to the timing means, the section being taken on line 4-4:, Fig. 2, looking in the direction of the arrows, and Fig. is an enlarged sectional detail of the timing means, the section being taken on line 5, Fig. 1, look ing in the direction of the arrows.

Similar reference characters designate like i parts in all the figures of the drawings.

The double-scoring machine shown herein is, or may be, in many respects the same or substzilntially the same as corresponding machines in general. use. lt embodies among other parts of well-known construction, a main frame, 2; a feed-table, 3, from which sheets are fed into the machine; primary scoring meelmnism comprising the usual bedroll, 4, and cooperative scoring knives, 5: a pair of feed rolls, 6, (l, by means of which successive sheets are fed from the primary scoring mechanism into position for delivery to the secondary scoring mechanism; a feed-table, 7, onto which said sheets are fed from the primary scoring mechanism; a reciprocatory feeddevice, 8, for feeding the sheets from said table 7 to the secondary scoring mechanism; and the secondary scoring mechanisn'i, 9, of similar construction and operation to that of the primary scoring mechanism. In connection with these parts suitable guides, stops, brushes, etc., are or may be en'iployed as in the ordinary machine of this type.

All of the parts of the double-scoring machine here shown may be operated from a suitable main driver, which in this case is the shaft, 10, carrying the bed-roll, 11, of the secondary scoring mechanism. From this shaft, movement is intended to be trans mitted through suitable driving connections both to the timing means for controlling the presentation of successive sheets to the primary scoring mechanism and also to the means for feeding to the secondary scoring mechanism sheets delivered onto the table 7 from said primary scoring mechanism. The connections to the timing means and to the last mentioned feeding means, which in this case is the reciprocatory feed-device 8. may be any suitable for the purpose.

Considering first the timing means for presenting sheets to the primary scoring mechanism, this comprises a feed device and means for bringing it into feeding relation with successive sheets in a predetermined manner, the object being to cause each sheet to be delivered to the primary scoring meChanism and associated pair of feed-rolls 66 at the same point in each cycle of operations of the machine, in order that each sheet may always pass through the machine in an exact predetermined relation to all of the submechanisms and elements that cooperate with it and are intended to act upon it. Here the timing means for feeding successive sheets into the machine embodies a feed-roll, such as, 12, and the feed-table 3, cooperative in such manner as to feed a sheet through between them at the proper moment and prevent the feed of a sheet at other times. In this construction the feedroll 12 is motmted on a long shaft, 13, extending transversely across the machine above the feed-table 3 and near the deliv ery end thereof, and the width of the pass between said feed-roll and the feed-table 3 is enough less than the thickness of the sheet to be passed through it as to assure the positive feeding of the sheet when the roll 12 is turned. Said roll 12 also serves, with the feed-table 3, to prevent the advance of a sheet through said pass when the roll 12 is not turning, and constitutes with said feed-table a positive stopping means for blocking the advance of sheets into the machine, except when they are being fed in proper timing by a turning of said roll. The shaft 13 and its roll 12 are mounted in pillow-blocks, 14, at opposite sides of the forward end of the feed-table 3. and may be adjusted up or down slightly relatively to said table according to the thickness of the sheets to be passed thereunder. At its lefthand end the shaft 13 carries a pinion, 15, constituting in the construction illustrated the terminal element of means for intermittently turning the feed-roll 12 at the proper times.

The operating means for turning the pinion 15 may be any suitable for the purpose. Here a large gear-wheel is shown at 16 as in mesh with. said pinion. This gear-wheel is illustrated as mounted for rotation on a stud, 17, projecting from the frame-work of the machine below the shaft 13. The gear-wheel 16 is normally stationary and is intended to be turned intermittently by a pawl-and-ratchet mechanism. Here said gear-wheel has secured to its outer face a ratclietwheel, 18, and the ratchet-wheel itself is operated by a pawl or pawls controlled by a suitable driver. The construction shown is one in which a four-armed wheel or star-wheel, 19, is also mounted on the stud 17, with its cheek in contact with the cheek of the ratchet-wheel 18. Each of the arms of this wheel 19 carries a springpressed pawl, 20, which, when said wheel is turned in the direction indicated by the arrows in Fig. 1, turns the ratchetavheel 18 and the large spur-gear 16 a corresponding distance in the same direction. At the same time the pinion 15 is also turned in the proper direction for feeding into the machine a sheet S which has been previously placed in position with its forward end in the pass between the feed-roll 12 and the feed-table 3, as shown in Fig. 3. To one of the arms of the wheel 19 is connected the forward end of a long rod, 21, which runs along the left-hand side of the machine and is connected at its opposite or rear end to one arm of a bell-crank lever, 22, pivotally supported by a stud, 23, depending from the under side of the feed-table 7. From the opposite or short arm of said bell-crank a connecting-rod, 24, extends in this case to a pin, 25, in fixed relation with the reciprocatory feed device 8 by means of which sheets are fed into the secondary scoring mechanism. By reason of these connections between the feed device 8 and the feed-roll 12 a predetermined relation between the movements of these parts is maintained throughout the cycle of operations of the machine. The feed device 8 is intended to be operated directly from the main driver of the machine, the organization of the parts be ing such that the to-and-fro movements of this feed device or pusher and the intermittent rotations and stops of the feed-roll 12, for advancing a sheet into the machine or preventing such movement, are both controlled from the main driver through connect-ions by means of which these two feed devices will be caused to operate in proper timing with each other and, indeed with all of the other operatively connected mechanisms and elements of the machine.

The reciprocatory feed device 8 is in many respects substantially the same as that disclosed in Letters Patent #1,054,962, issued March 41, 1913. It is preferably a light feed-plate having a. short stmketo permit of operation at high speed and it is disposed and operative to engage one edge of a sheet delivered onto the feed table 7 and push the sheet to the secondary scoring mechanism. As in the aforesaid patent, it carried by a slide mounted to reciprocate in a suitable way disposed substantially centrally of the feed table 7. In certain respects, however, this reciprocatory feed device or pusher 8 differs from that of the aforesaid patent. Here it is formed with a vertical rib, 42. for engaging the adjacent edge of a sheet, which rib is made relatively high to prevent possibility of the feed device passing under a warped or similarly distorted sheet and so failing to feed the same. The feed device here shown also has a foot or member, all, projecting forwardly from the base of the rib 42 a suiiicient distance to eXtend beneath the edge of a sheet being fed onto the feed table '7 when the feed-device has reached the limit of its backward stroke. \Vith the feed device thus constructed all possibility of the sheets going either under or over the same in the operation of the machine is avoided. The operating connections for this reciprocatory feed device 8 may be any suitable for the purpose. Here the pin 25, to which is connected one end of the connecting rod 24 for actuating the sheet-timing feed roll 12 as hereinbefore described is carried by the reciprocatory slide 26 with which the said feed device 8 is connected, and said slide is connected with one end of a pitman-rod 27, the other end of which is pivotally connected to the crank 28 of a. crank-shaft 29. This crank-shaft may be operated to impart re ciprocating movement to said slide and connected parts in any suitable manner. In the construction shown the main driving shaft 10 carries a band-wheel, 30, from which a belt, 31, passes to a corres mnding bandwheel, 32, on a counter-shaft, 33, parallel with the crank-shaft 29, this last named shaft being driven by a cone drive, 34, 35, 36, from said counter-shaft by means of which any desired variations in speed may be obtained by simply shifting the belt 36. This cone drive constitutes, as will be clear, a means for changing the speed of the machine to suit different kinds of work.

The primary and secondary scoring mechanisms, including the feed-rolls and various other operative parts associated therewith, are or may be driven in usual manner from the main driver 10, so that all of the working parts of the double-scoring machine shown in the present application are operatively connected for movement through a certain predeteinnined cycle of operations in which the travel of each sheet through the machine is mechanically predetermined and controlled, the feed of each sheet being positive and the mechanism being so timed and coiii 'ierating in such a manner that every sheet is started into the machine at the same point in the cycle of operations.

The operation of the machine shown as follows: The operator takes a sheet from a pile and pushes it against the timing feed-roll 12 which, at the proper point in the cycle of operations, begins to turn and thereby is brought .into feeding relation with the sheet which it feeds forward far enough to be caught by the scoring knives and feedrolls of the primary scoring mechanism. is the sheet passes through the primary scoring mechanism onto the feed-table T the reciprocatory feed device 8, which is connect:- ed with said timing feed-roll 12 by the mechanism previously describe l, is about at the rear end of its stroke and is ready to pick up said sheet which has been fed out onto the table 7. The operator then thrusts an other sheet against the timing feed-roll 12 at the entrance of the pass between it and the feed-table 3, said feed-roll being at that time at rest and operative as a sheet-stop, with the pawls 20 moving backward over the teeth of the ratchet-wheel. 18. After the reciprocatory feed device 8 has moved forward, carrying the first sheet on the feedtable 7 through the secondary scoring met-hanism, the second sheet is also fed forward through the primary scoring mechanism by the timing feed-roll 12 actuated by the linkage from the reciprocatory feed device 8 as said device moves toward the rear end of its stroke; and this second sheet reaches the end of its movement in this path, as previously stated, at about the time the feed device 8 is at the end of its back stroke and said sheet is then in position to be fed through the secondary scoring meclmnism as the first or preceding sheet was. Thus in the operation of the machine the timing feed-roll 12 is intermittently turned to feed a sheet into the machine and is then stopped, and the feed device 8 makes one complete stroke, both inthe same cycle and inv predetermined timing in such a manner that a single sheet is fed through the machine at each stroke of said feed-device and it is im possible for two sheets to interfere with each other in the machine or for a sheet to fail to travel steadilyin a predetermined manner through both the first and second scoring mechanisms. In a machine of this type the scoring rolls may be operattal at higher speed than in machines as heretofore constructed and increased capacity thus obtained.
